Question

Researchers studied the effects of learning about the effectiveness of a new medication (Tal & Wansink, 2014). Some participants heard information about the medication; others heard the same information and saw a graph that depicted the data they had heard about. Thus, the two groups had identical information. Participants rated the effectiveness of the medication on a scale of 1-9, with 9 indicating a higher level of effectiveness. The researchers reported "Participants given graphs expressed greater belief in the claims, rating the medication as more effective (6.83 of 9) than did participants given verbal description only (6.12 of 9)." The results were statistically significant. The researchers titled their paper "Blinded with Science" because the mere presence of a scientific cue - a graph - altered perceptions of medication.
